some applications store gigantic quantities of image meta-data in certain tags, and LibTiff happily allocates gigantic quantities of RAM to store this tag data, when all I really want is to query the image dimension or DPI tags.
i see the TIFFReassignTagToIgnore function, but i'm not sure it actually does anything... the arrays it fills aren't used anywhere.
Do you really need only an ignore mechanism, for your purposes, or do you need a lazy read mechanism that doesn't actually read the tag value until it is first time queried?
